# this is my first script - so maybe some things are not the best way to do it 🙈

# I didn't use defaults -currentHost write .GlobalPreferences com.apple.mouse.swapLeftRightButton -bool false
# because you need to logout and login again

# ATTENTION: sometimes it works, sometimes it doesn't - I don't know why
# Hints would be really appreciated ;-)
# error "System Events got an error: Can’t get tab group 1 of window 1 of application process \"System Preferences\". Invalid index." number -1719 from tab group 1 of window 1 of application process "System Preferences"
